I have this game that I play usually a while everyday. Yesterday I went to start it and got an error. It said "Microsoft Visual C + + Runtime Library. This application has requested the Runtime to terminate it in an unusual way." Please contact the application's support team for more information.
I believe the cause was the Flashplayer update I did because that is when it messed up.
Can you please help me as I really love the game? The game is Hexus.

There seems to be several games with that name so you need to describe it better.

Perhaps your game uses something from the runtime library that Flash changed. You could try reinstalling the game to see if that corrects the problem.
Just be sure to keep a copy of your "save-game" so that you don't need to start over.
